Description

A flaw was found in the btrfs filesystem component of the Linux kernel. This vulnerability arises from a race condition when multiple threads within the same program attempt to use the lseek(2) system call concurrently on the same file. An attacker could exploit this to cause a memory leak or a use-after-free error. A use-after-free error can lead to system instability, crashes, or potentially allow for arbitrary code execution.
